ROAD-VEHICLE WHEEL.

matinee Application filed November 19, 1910. Serial No. 593,211.

To all-whom it may concern:

Be it known that I, JOHN ALLAN CECIL "WRIGHT, a subject of GreatBritain, residing at Birniingharn' England, have invented new andusefulImprovements Relating to Road-Vehicle l Vheelaof which the following isa specification. i

This invention relates to road vehicle wheels which are proyid-ed withdetachable rims of the type comprising a gapped annulus provided withtire retaining flanges,

. and fitted with a detachable segmental por tionalso provided with tireretaining flanges and which when in position commoved from "oppositesidesof the wheel rim, and-also the connection by cottersxortheir-eguiyalen't to the inner-side of the adjacent ends of the rim of aplate to which i the said parts are secured, so that with the tighteningofthe cotters the ends of the rimare drawn together to produce tightjoints at theends of thedetachable parts, or expanded for liberationfrom the Wheel.

Referring to the two accompanyingsheets of explanatory drawings ;-Figure1 is a side elevation and Fig. '2 a cross section of a mo tor vehiclewheel constructed in accordance with this'inveution. Fig.3, is a plan ofa part of the wheel showing the detachable segmental "portions removedfrom the rim and Fig. a is a sectional plan of the same partshowing thesegmental portionsin position. Figs. 5, 6 and lare respectively crosssections through the wheel, rim on the lines 'l-2, via-4:, 56, Fig., 1QFigs. 3 to 7 Specification of Letters Patent.

Patented Aug" $9, 19110 are all drawn to a and 2. i v sThesainereference letters in the vdifferent views indicate the vsameparts. a

The wheel shown comprises a folly a to which are secured the spokes b inthe ordinary manner. The folly is provided with a metallic band 0, andon this is mounted a detachable rim comprising am ic ring Z carrying theusual pneumatic or other resilient tire and a reinforcingavood annulus@f The inner surface oitthe latter and the outer surface oft-he telly aare made to larger scale than Figs. 1

a tapered configuration as shown. In. the

application of the invention to'such, a wheel both the part '03 and thereinforcement 'e of the detachable rim are gapped as heretofore, andacross the gap is arranged a metal plate f so that it occupies a-centralposition between the opposite edges oi the rirn andis perpendicular tothe underside of the part (Z. The detachable segmental portion isot thesame section as the rim and is divided centrally into two parts, or inother words consists ottwo parts 5/. Each partis preferably made so thatwhen two parts are in position they fill the gap between the ends of therim and complete both the inner and outer periphery of the rim. Acontinuous surface is therefore providedfor supporting the pneumatictire and also for embracing the outer periphery'of the felly'a; Thesegmental parts are doweled together by pins 7L which pass through the"central plate f'and are. secured by zi -transverse screw vawhichient'ers a nut or screwed aper tare ,provided in one of the saidparts.

I To detach the segmental parts from vthe rim, the itransv'erse screw isreleased and the parts can then be separatedsidewise and respectivelywithdrawn fronrvthe opposite sides of the rim as showninFig; 3. Byconstructing the segmental. portion in :two

parts and arranging for them. to vbe sepa rated .or placed together fromthe opposite sides of ;the ,wheel, a great convenience s providedin theremoval [or replacement of the tire, as the parts can be detached orrebe, ted or thickened edges of the tire. When the parts are removed theends of the' rim can be drawn together by any convenient means (such asa detachable right and left hand coupling screw fitted with ratchetoperating lever and attached by any'convenient means to opposite ends ofthe rim) for diminishing the diameter of the rim and enabling the tireto be easily removed or replaced. I

The plate f above referred to for connecting together the ends of therim and supporting the detachable parts is preferably secured by a pairof transverse tapered cotters j fitted with external nuts Each cotterpasses through a pair of metal plates Z riveted to the inner side of therim as well as through the plate f. It will be observed that the ends ofthe plate f areplaced between the plates Z. The plate f is provided withslots we so that the cot'ters do not interfere with the contractilemovement aforesaid. Also the plates Z are slotted adjacent to thecotters to permit a sufficient axial movement of the lattertherethrough. Suitable holes ,are formed in the wood annulus to receixethe cottersas shown. By means of the cotters the rim ends can be pressedtightly against the ends of the detachable parts af-.

' when it is required to remove the rim are reinforcement c.

The invention is not limited to rims with .inner wood reinforcements asit may be applied to other rims of the gapped type, nor is it limited toany particular means for securing' the segmental parts in position.Alsothe invention is applicable to wheels having wire spokes as well asto'wheels with wood spokes. 1

For securiifg the rim to the wheel, a convenient device comprises anumber of'bolts n p assed laterally through the wheel. Each bolt engagesa fixed nut 0 in the wheel and has provided on it a sleeve p with anexternal' claw g for pressing against the side of the detachable rim. Onslackening the bolt the sleeve is pushed outward by a shoulder on thebolt, so that the claw on the sleeve can be freely turned into anunobstructive posi tion. With all the bolts released the rim can bereadily removed. Ontightening the bolts with the claws in the operativepositions after the rim has'been replaced on the wheel, the rim isfirmly secured.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In road vehicle wheels, the combinationwith a gappedsannulus provided with tire retaining flanges, of aplate-connecting the ends of the annulus, and a pair of laterallymovable segmental parts provided with tire retaining flanges adapted tobe detachably secured on opposite sides of the plate and complete theannulus, substantially as described.

2. In road vehicle wheels, the combination withfan annulus formed with a.gap and adapted to receive a detachable tire around its outerperiphery, of a slotted plate connecting the ends of the annulus,fastenings passin through the slots in the plate and the ends of theannulus, and a pair of laterally movable segmental parts adapted to bedetachably secured on opposite sides of the plate and complete theannulus, substantiallyas described.

3. In road vehicle wheels, the combination with an annulus formed with agap and adapted to receive a detachable tire around its outer periphery,of a slotted plate connecting the ends of the annulus, tapered'cotterspassing through the slots in the plate and the ends of the annulus, anda pair of laterally movable segmental parts adapted to be detachablysecured on opposite sides of the plate and complete the'annulus,substantially as described.

4. In road vehicle wheels, the combination with an annulus formed with agap and adapted to receivela detachable the around its outer periphery,of plates attached to the inner sides of the ends of the annulus, aslotted plate connecting the ends of the annulus, fasteningspassingthrough the plates, and a pair of laterally movable segmental partsadapted to be secured on opposite sides of the plate connecting the endsof i the annulus and complete the latter, substantially as described.

5. In road vehicle wheels, the combination with an annulus formed with agap and adapted to receive a detachable tire around its outer periphery,of a plate connecting the ends of the annulus, a pairof lateraiy mov--able segmental parts placed on opposite sides of the plate and adaptedto complete the annulus, dowels attached to one part and arranged topass through the plate'and enter holes in the other part, and a securingbolt passing through the said parts and the plate, substantially asdescribe 6. In road'vehicle wheels, the combination consisting of adetachable and contractible rim formed with. a gap and adapted toreceive a detachable tire around its outer periphery' a pair oflaterally movable segmental parts adapted to be secured in the gap andto complete the rim, an inner Wood reinforcement for the rim, a fellyadapted to receive the said rim, and means for detachably securing therim in position, substantially as described.

In testimony whereof I have slgned my 15 name to this specification inthe presence of two subscrlbmg Witnesses.

EDWARD MARKS, JOHN MORGAN.
